Why

ss is a powerful tool, but it not very good for my use-case:

• Parameters. Is -loptun a good combination? I don't know.
• Output for one socket may be broken into multiple lines.
• Related sockets aren't always grouped together.
• The command name isn't helpful when it's python or node.
• The listening address isn't helpful with v6 addresses.

lls aims to do better:

• No command line parameters necessary
• Compact output (but hopefully not an eyesore)
• Grouping sockets by process and port
• Conservative command line parsing to show script names for interpreters
• Pair listening addresses with interface names

lls's Issues

Tag the source

Could you please tag the source? This allows distributions to get the complete source from GitHub as tarball instead of working with commits which point to the different versions.

Thanks
